(Greek mythological name). Written also Callirrhoe. Malvaceae. Hardy showy herbs, for outdoor planting.

Perennials or annuals: leaves alternate, with lobed or cleft blades or more finely dissected: flowers showy, axillary or sometimes in terminal racemes, the petals irregularly cut at the apex or truncate, differing in this from the notched petals of Malva; involucel of 1-3 bracts, or wanting. - Nine species, native.

The callirhoes are of the easiest culture, and deserving of a much greater popularity. They are chiefly propagated by seeds, but the perennial species may also be propagated by cuttings.
